Embodiment Construction

[0047]Referring more specifically to the drawings, for illustrative purposes the present invention is embodied in the apparatus generally shown in FIG. 2 through FIG. 13. It will be appreciated that the apparatus may vary as to configuration and as to details of the parts, and that the method may vary as to the specific steps and sequence, without departing from the basic concepts as disclosed herein.

[0048]FIG. 1 illustrates a simplified lateral view of a portion of the cervical spine 10. The basic biomechanical unit or motion segment of the spine consists of two adjacent vertebrae 12 and 14 and the three joint articular complex through which they move and are constrained in relation to one another. The spine articulations generally consist of an intervertebral disc 26 located between the vertebral bodies 26 of adjacent vertebrae 12, 14, and two facet joints 16 symmetrically located laterally from the sagittal plane at the posterior end of the vertebral bodies 26.

Abstract

A device and method for a minimally invasive surgical implantation to reduce radicular symptoms by inserting an expandable cervical distraction implant in the facet joint and distracting the adjacent cervical vertebrae to increase the foraminal dimension. The implant, when positioned in the cervical facet joint, expands to via delivery of an inflation medium to increase the space between the vertebrae, thereby increasing the foraminal area or dimension, and reducing pressure on the nerves and blood vessels of the cervical spine.
